Graph the following points on the graphing calculator:
Nimfa-mama [501]
Brainly says you need the following points

- The pattern is min-zero-max-zero-min, which is the pattern for a cosine function of the form y = acos(x) + k, but is reflected over the x-axis (so a < 0).
- The amplitude is |a|, so a = –1 and |a| = 1.
- The midline is exactly between the max and the min, y = (6 + 8)/2 = 7, so k = 7.
- The equation is y = –cos(x) + 7.

pavit has a clock with a minute hand that extends to the clock's edge. The minute hand is 5 inches long. What is the circumferen
Eddi Din [679]

Answer:

The circumference of the clock is 10\pi\ in

Step-by-step explanation:

we know that

The circumference of a circle (clock) is equal to

C=2\pi r

In this problem

The long of the minute hand is the radius of the circle

so

r=5\ in

substitute

C=2\pi (5)=10\pi\ in -----> exact value of the circumference

A trapezoid has an area of 80.75 sq. in., and its two bases are 7 and 12 inches long. Find the height of the trapezoid. a. 8.5 i
charle [14.2K]
<span>The formula is area of trapezoid = average base x average height 

We're going to do this in reverse.

Area = 80.75
[(7 + 12)/2] = 9.5 (height)
height = 80.75 / 9.5 = 8.5 

The height is 8.5, so the answer is D.</span>

Alex is building a rectangle fence around his yard. the total perimeter of the fence is 68 feet and the area of his yard is 240
Alisiya [41]

Let's call the length of the rectangular fence l and the width of the rectangular fence w.


Based on the information in the problem, we can make two equations, based on the formulas for perimeter and area:

A = lw

P = 2l + 2w


Now, let's substitute in the values we are given in the problem:

240 = lw

68 = 2l + 2w


Now, let's solve the system using substitution.

240 = lw \Rightarrow \dfrac{240}{w} = l

  • Solve for l from the first equation

68 = 2\Bigg( \dfrac{240}{w} \Bigg) + 2w

  • Substitute this value into the second equation

68 = \dfrac{480}{w} + 2w

  • Simplify

68w = 480 + 2w^2

  • Multiply both sides of the equation by w

2w^2 - 68w + 480 = 0

  • Subtract 68w from both sides of the equation

(2w - 48)(w - 10) = 0

  • Factor

2w - 48 = 0 and w - 10 = 0

  • Use the Zero Product Property and solve both factors

2w - 48 = 0 \Rightarrow 2w = 48 \Rightarrow w = 24

w - 10 = 0 \Rightarrow w = 10


We are given two possible lengths. However, the funny thing is that both produce the same dimensions: 24 ft by 10 ft:

w = 24 \Rightarrow 240 = l(24) \Rightarrow l = 10

w = 10 \Rightarrow 240 = l(10) \Rightarrow l = 24


Thus, our answer is Choice C, or 10 feet by 24 feet.
